It may be most likely but the firing vavle is also a less likely possiblity. Easily tested by closing the bolt, and seeling if a soapy film on the muzzle/silencer causes bubbles.
Always looking for any cheap, interesting, knackered "project" guns. But not lathes. I have too many lathes. Thanks, JB.
